       The parameters in this table are updated when a measurement

       Note that a bits-per-subcarrier measurement is also performed
       during a line diagnostic procedure.  This table provides an
       additional mechanism to fetch the bits-per-subcarrier data.  This
       additional mechanism is provided so that bits-per-subcarrier
       data may be fetched without forcing the line into no power state.
       This is useful because the bits-per-subcarrier allocation may be
       adjusted at Showtime due to rate adaption and bit swapping.

       The implementation of this additional mechanism for measuring
       bits per subcarrier is not mandatory."

      responds with the value 'wrongValue' in the error status
      field of the response-PDU.

      The SNMP agent may have limited resources; therefore, if multiple
      rows coexist in this table, it may fail to add new rows to this

     DESCRIPTION
     "This parameter contains the number of symbols used to measure
      the SNR(f) values.  It is an unsigned integer in the range from 1
      to 2^16-1.  After a loop diagnostic procedure, this parameter
      shall contain the number of symbols used to measure the SNR(f).
      It should correspond to the value specified in the Recommendation
      (e.g., the number of symbols in 1 s time interval for ITU-T
      Recommendation G.992.3)."

     DESCRIPTION
     "Row Status.  The SNMP agent will create a row in this table
      for storing the results of a DELT performed on the associated
      line, if the row does not already exist.

      When a row is created in this table, the SNMP agent should also
      create corresponding rows in the tables xdsl2SCStatusBandTable and
      xdsl2SCStatusSegmentTable.

      The SNMP manager is not permitted to create rows in this table or
      set the row status to 'notInService'.  In the first case,

Top      Up      ToC       Page 90 
      if the SNMP manager tries to create a new row, the SNMP agent
      responds with the value 'noCreation' in the error status
      field of the response-PDU.  In the latter case the SNMP agent
      responds with the value 'wrongValue' in the error status
      field of the response-PDU.

      When a row is deleted in this table, the SNMP agent should also
      delete corresponding rows in the tables xdsl2SCStatusBandTable and
      xdsl2SCStatusSegmentTable.

      The SNMP agent may have limited resources; therefore, if multiple
      rows coexist in this table, it may fail to add new rows to this
      table or allocate memory resources for a new DELT process.  If
      that occurs, the SNMP agent responds with either the value
      'tableFull' or the value 'noResources' (for
      the xdsl2LineCmndConfLdsfFailReason object in xdsl2LineTable).

      The management system (the operator) may delete rows from this
      table according to any scheme.  For example, after retrieving the
      results."
